Synthesis, characterization, and application of Ba3V2O8 ceramics in cylindrical dielectric resonator antenna: Simulation and experimental study
This study focuses on synthesizing dielectric ceramic material Ba3V2O8 (BVO) and its application in Cylindrical Dielectric Resonator Antennas (CDRAs) fabrication. The investigation involves a comprehensive parametric study combining software simulations and experimental validation to understand the performance characteristics of the CDRA using the synthesized material. The ceramics were sintered at 900 °C and 950 °C. X-ray diffraction (XRD) confirmed the phase formation, indicating a Rhombohedral structure with the space group . Dielectric properties were characterized, revealing temperature-independent structures. The dielectric properties of BVO ceramics (BVO-900: =13.1, =4000, =0.00222, =0; BVO-950: =13, = 5000, =0.00173, =0) were utilized to model CDRAs using the High-Frequency Structure Simulator (HFSS) suite. The designs were optimized for effective performance and used to fabricate CDRAs, which were subsequently characterized using a network analyzer and a double-ridge horn antenna. The CDRA using BVO-900 exhibited resonance frequency ( = 8.06 GHz, S11 = -44.02 dB, Voltage Standing Wave Ratio (VSWR) = 1.07, and Bandwidth (BW) = 16.25 %, while the BVO-950-based antenna displayed = 8.09 GHz, S11 = -30.49 dB, VSWR = 1.06, and BW = 13.1 %. Measured values closely matched simulated values, demonstrating the effectiveness of the synthesized ceramics in CDRA applications.
期刊介绍：
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
